[FEATURE] Allow to interpret the stdout of hooks

Preflight Checklist

• [x] This is a single feature request (not multiple features)

Problem Statement

Currently, apart from UserPromptSubmit, hooks do not read stdout as context.

However, I believe that supporting this in other events as well could greatly enhance extensibility.

For example, before reading a specific file, the system could also load additional context, enabling more context-rich operations.

Proposed Solution

Add a flag to control whether Claude Code uses the hook’s stdout as context.

Alternative Solutions

I can't find alternatives
